Extracorporeal Shock Wave Lithotripsy and Combined Therapy in Children: Efficacy and Long-Term Results.

Background: Extracorporeal shock wave lithotripsy (ESWL) is nowadays the first choice for the treatment of upper urinary tract stones smaller than 2 cm, considering its low complications and high success rate. Aim: To present an update of the current situation of ESWL treatment and to analyse our series of patients and the efficacy of combined lithiasis treatment in different locations and sizes. Patients and Method: Retrospective study including patients with urolithiasis treated with ESWL between 2007 and 2019. Collected data included: gender and age at treatment, presentation symptoms, imaging studies, stone location and size, complications and stone clearance. Success was defined as stone-free status or the presence of clinically insignificant residual fragments (<4 mm after 3 months follow-up). Patients with residual stones larger than 4 mm after 3 months were programmed for another ESWL session or received a combined sandwich therapy, followed by URS or percutaneous approach. Results: Between 2007 and 2019, 37 patients presented a total of 41 lithiasis episodes that were treated with ESWL sessions. Median age at first procedure was 9 years old (1-17) and median follow-up time was 6 years (3-12). Stones were located in the renal pelvis, followed by the lower, middle and upper calyx, proximal ureter, and 51% of our patients had multiple lithiasis. Median stone size was 12 mm (5-45), the main component being calcium oxalate (34%). During immediate postoperative period, 8 patients (19%) presented complications: renal colic, hematuria and urinary tract infection. After the first ESWL, 41% of the patients (n = 17) were stone-free. Out of the 24 residual lithiasis episodes (58%), three patients (7%) underwent a second ESWL session. In the remaining 19 patients, ESWL was combined with URS or percutaneous approach to achieve complete stone clearance. Overall stone free status after combined therapy was 95% (n = 39). Conclusion: These data support that ESWL is an effective minimally invasive technique, with low cost and morbidity, reproducible and safe for the treatment of stone disease in children. Even though lithiasis size seems to be a significant factor in ESWL success, in combination with other lithotripsy procedures it can reach very high rates of stone clearance.

[Medium-term results of the endourological management with balloon dilatation of the ureteropelvic junction stenosis in infants]. / Resultados a medio plazo del tratamiento endourológico retrógrado con balón de la estenosis pieloureteral en niños menores de 1 año.

AIM: In the last years it has spread minimally invasive therapeutic for the treatment of pyeloureteral junction obstruction in children. Some of them have got poor outcomes in 4-year-old minor children. We show our experience in the retrograde dilatation with balloon of high pressure in infants. METHODS: It's a retrospective study of 16 infants treated in our hospital. The average follow-up after the intervention is 27.4 +/- 10.0 months. The diagnostic protocol included abdominal ultrasound, cystogram and diuretic renography. The treatment was realized by endourology retrograde balloon dilatation under fluoroscopy. The balloons were in all the cases semicompliant, with a profile of 5 mm, 6 mm 6 7 mm. After the expansion there was placed stents type double J with profile and length depending on the weight of the patient. To obtain the results, we do ultrasound scans and diuretic renography at least 1 year after the intervention. RESULTS: The mean duration of the intervention was 36.4 +/- 15.5 minutes. During the intervention, in 2 patients the placement of the stent was not possible. The time of revenue was 48 hours in all the patients except in 1 of them. The analgesic needs were exclusively non steroid antiinflammatorys. The double J stent was withdrawn with cystoscopy. In 3 patients there were postoperatory complications: a migration of the stent, a urinary infection and an urinoma. In 1 patient with worsening of hydronephrosis was needed of pyeloplasty. In the controls the disappearance of the hydronephrosis was observed in all the cases, eliminating likewise the expansion of the renal calyces. The diuretic renography improved in all babies, being the boss of the curve normal in 14 cases and semi obstructively in 2. The mean time of elimination was 9.8 +/- 2.8 minutes. CONCLUSIONS: We think that the balloon dilatation of pyeloureteral junction obstruction is a minimally aggressive technique that is possible to realize in infants with good results and scanty complications.
